Definition : Compression (of a gas, plasma, etc.) not accompanied by gain or loss of heat from outside the system. For a plasma in a magnetic field, a compression slow enough that the magnetic moment (and other adiabatic invariants - see entry) of the plasma particles may be taken as constant.

The Plasma Dictionary is based on the Fusion & Plasma Glossary that was originally created on FusEdWeb, Fusion Energy Educational Website which has additional introductory information on plasma and fusion science .

A planet (from the Greek planete means "wanderer" or
more forcefully "vagrant, tramp") is an object in orbit around a star
that is not a star in its own right. Much like "continent," "planet"
is a word without a precise definition, with history and culture playing
as much of a role as geology and astrophysics

This is a "living glossary". This means that the glossary may grow every week as individuals submit new entries. This has been set up as a class resource for CEM-181H, the freshmen honors chemistry lecture at Michigan State University.
